If your looking for the percent you do 35 × 100, then divide by 175. You should get 20% as your answer.
If the legs are length a and b and hyptonuse is c then
a²+b²=c²
so
if the legs are 20 and 21 and the hypotnuse is x then
20²+21²=x²
400+441=x²
841=x²
29=x
The second one should be correct
Answer:
x=-6
Step-by-step explanation:
2x=-4-8
2x=-12
